I've been running my own PVR for years now, recording standard definition DVB-T in the UK on a box based on WinXP and GBPVR. Basically, I need advice as to what CPU I should be upgrading to to do what I do now but with high def DVB streams. What CPU should I be looking at to put in my box that will allow me to record two high def DVB streams and watch a third, all at the same time? I currently use an underclocked Athlon XP-M@1.6GHz to do this with standard def streams.
I will of course also be getting a new mobo, RAM, and probably DVB cards if it turns out my Hauppauge PVR-250s won't handle it.
